Best Practices

Over time, serpentine belts crack, become glazed, and can squeak or even break. For optimal performance and reliability, they should be replaced at the recommended interval by the manufacturer.

We recommend replacing serpentine belts if related components are being repaired and the belts have signs of wear or have over 30,000 miles on them.

We recommend replacing all the BMW 135i drive belts as a set, so that they wear evenly.
